i found an commercial already deployed LoRaWAN gateway. inside the case, i found an NanoPi NEO core (http://nanopi.io/nanopi-neo-core.html) with unknown Lora transceiver cards. all combind with an PCIe shield board (3 PCIe slots available). two of this PCIe slots are slotted with (for me) unknown transceiver, maybe someone can help, see picture.
my question, is an already given chirpstack gateway OS ready for this hardware setup?
